A flat tire is a bad time, and a portable air compressor is the simplest way to ensure it doesn’t become a very bad time. Keeping a tire inflator stashed in every car you own (and your garage) is a no-brainer for drivers (and inflatable ball users) who want to be prepared, and Walmart is doing its part to make this kind of tire inflator more accessible with a massive discount on a well-reviewed model.
The Cowin Tire Inflator is on sale for $15 at Walmart, 62% off its normal $40 price tag. That’s a tiny price to pay for the peace of mind and convenience this device has to offer.
62% OffPros
- Four different preset modes and a manual pressure option
- Onboard LED to help out if you’re inflating a tire at night
- Bright LCD display and ultra-compact design
Cons
- Air hose is on the shorter side, so you’ll have to spend a lot of time stooped over while inflating
The first thing you’re likely to notice about this tire inflator is how small it is, as just 6.2 inches on its longest size with a featherlight weight of 2.89 ounces. It can push out up to 36 liters of air per minute to a pressure up to 150 PSI thanks to the powerful air compressor that runs on a 25,000mAh battery that recharges via the included USB-C cable. An onboard light, easy to read display, and ability to pull double duty as a power bank round what’s an impressive feature set, particularly for just $15.
One shopper wrote that this “small but powerful tire inflator” took a “flat tire with 5 PSI of air pressure to 36 PSI in just two minutes.”
Other customers agreed, calling this device a “fast and lightweight” tire inflator that makes it “easy and quick to inflate my tire to the correct pressure.” Another called it “quick and easy to use with a light as well.”

The Cowin Tire Inflator is small enough that you might forget you have it in your car and useful enough that you’ll be happy you did the next time a tire or ball needs inflating. For $15, it’s a supremely good value, the kind of device that can pay for itself with just one use. Do yourself a favor and grab one (or a few) before this deal disappears.
